What Large Ears You Have!
Townsend's Big-eared bats have ears that are up to 4 cm long... which is half its body length! Equivalent ears on a human would be a whopping 2-3 feet long! These big ears are thought to promote lift when flying and help with temperature regulation. they prefer to roost in more open spaces like caves, buildings, and hollow trees instead of in tight crevices or bat boxes.
It is about time for these bats to start hibernating and they will overwinter here in BC. Remember to never intentionally disturb a bat roost in the winter - waking up from hibernation burns a lot of energy and too much disturbance can result in bats not having enough energy to see them through until spring. More than half of our bat species in BC are either threatened or endangered so it is important for everyone to do their part to stop any further decreases.
